Location: Rhinelander, Wisconsin | The mag has a pad, but no built in set back.
Tuffy recommends the high speed transducer is placed between the bunks in the tunnel area of the sponsons on the starboard side close to the lift strake; that's where the cleanest water flow is at high speeds. The surface of the transducer should be dead even with the running bottom with the rear of the 'ducer tipped down about 3 degrees. As mentioned, the side imaging unit doesn't need to be placed the same, as it's used at slow speeds. The difference between the two pictured mounts as far as a clear shot past the front of the lower unit is the built in set back on the second; it provides a bit of extra space between the side scan 'ducer and the front of the lower unit and it appears the transom angle is a bit sharper on the Ranger in the mount area. The 1890 and 2060 have built in set backs, the 1700 has a true V hull, and the 1760 has a semi-high performance running bottom. The Mag is a sponsoned V, and has a pad created when the original Marauder hull was split and widened to make the Magnum 80" wide from the original 70" design. |
